Definitions

  • the lighting of this type of transparent plate, with or without an opaque background, is traditionally carried out by one of the sides of the plate.
  • the opposite and perpendicular sections are either closed by profiles, adhesive strips, or other accessories intended to recover more or less the light, or left free and polished then letting escape a large part of the illumination of the plate, especially when the source bright is away from the edges.
  • the best known example relates to road signs, in particular that of streets, or the intaglio engraving by the reverse of the letters constituting the names or names of the streets, seen through the transparent surface of the unpainted face, are brightly lit at the beginning of the text, then more and more dimly as these letters become more and more distant from the light source.
  • the invention aims to provide solutions to the specifications thus constituted from the 1st to the 5th point described above.
  • the invention therefore relates to a reflector device for light display on the opaque background of a transparent plate, for information, advertising or indicative signage, interior or exterior.
  • a transparent plate (1) made of cast polymethyl methacrylate, or of polycarbonate with a shiny or anti-reflective surface, having a refractive index higher than that of glass, which plate is opacified on its rear face (7), by means of an acrylic paint or any other material, machinable after drying, and adhering perfectly to this face.
  • a thread (6) is formed at a distance (D) from the 3 lateral edges, constituted by a groove of a few millimeters in cross section (X), and a depth (Y) less than 1 to 2 m / m to the thickness of the plate, this net will be filled with an adherent light opaque shade, thus intended to reflect the light, on the surface thus delimited and reserved for inscriptions (15).
  • These inscriptions, signs or graphics (15) will be before or after, printed, glued, engraved or included upside down, through the opacified layer (7) to be seen in relief, or not, by transparency and at the place.
  • the 4th lateral edge (2) will be enclosed on 2 cms in a hollow core profile (3), closed at the 2 ends, and will receive above and in the axis of the angle of 105 to 120 ° formed by the edge and the bevelled edge, opposite the opaque face, the light source (8) composed of a linear or fractionated light tube, and its accessories.
  • the circular reflective net (6) machined in the same way as in the first characteristic will surround the surface reserved for inscriptions (15).
  • a small printed electrical circuit (20) will be slipped in there made up of micro-lamps (18) welded together in parallel, hidden from view, on the transparent side, by a plate (5) added and glued 15 m / m high preferably a homogeneous opaque material, and in the same material as the transparent plate.
  • the same lamps (18) will illuminate the plate with an opaque bottom, which must be provided with the reflective mesh always machined in the same manner as according to the 1st characteristic, at a distance (D) from the three other lateral edges.
  • the device which is the subject of the invention constituted by the reflective net (6) can be applied to other types of embodiments, on all types of transparent plates with opaque background, in equivalent materials, with the addition of elements which would then be unrelated to any inventive contribution.
  • the invention is particularly indicated in the manufacture of street signs, signs of all types, number plates of all vehicles.
